As she tackles each meeting, Sandberg also stays on track by checking off tasks in a “decidedly un-digital spiral-bound notebook,” according to Fortune’s Miguel Helft. Once every item on the page is checked off, she rips it out of the book.

When she joined Facebook in 2008, Sandberg also brought along a new routine of “check-ins.” At the start of every leadership meeting, participants can go around the table and discuss their “emotional and professional state,” according to Bloomberg.

It’s a quick way for the team to stay connected and feel heard before they get down to business.
